This Chicken Parmesan Casserole packs all the flavors of classic chicken Parm into one easy, crowd-pleasing bake. Tender shredded chicken is tossed in garlicky marinara, layered with melty mozzarella and Parmesan, then finished with a golden, crunchy breadcrumb topping for a cozy dinner that feels comforting yet weeknight simple.
Ingredients
- 4 cups cooked chicken, shredded (rotisserie chicken works great)
- 2 cups marinara sauce
- 2 cups mozzarella cheese, shredded, divided
- 1 cup Parmesan cheese, grated, divided
- 1 cup breadcrumbs (plain or Italian-style)
- 1 tablespoon Italian seasoning
- 2 cloves garlic, minced
- 1 tablespoon olive oil
- Salt and pepper to taste
- Fresh basil, chopped or torn, for garnish
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish and set aside.
- In a large mixing bowl, combine the shredded chicken, marinara sauce, half of the mozzarella cheese, half of the Parmesan cheese, minced garlic, Italian seasoning, salt, and pepper. Stir until the chicken is evenly coated and everything is well mixed.
- Transfer the chicken mixture to the prepared 9×13-inch baking dish, spreading it out into an even layer.
- In a separate bowl, add the breadcrumbs, remaining mozzarella cheese, and remaining Parmesan cheese. Drizzle with the olive oil and toss until the breadcrumbs are evenly coated and slightly moistened.
- Sprinkle the breadcrumb-cheese mixture evenly over the chicken layer, covering it completely for a crunchy topping.
- Bake in the preheated oven for 25–30 minutes, or until the top is golden brown, the cheese is melted, and the casserole is hot and bubbly around the edges.
- Remove from the oven and let the casserole cool for 5–10 minutes to set slightly before serving.
- Garnish with chopped or torn fresh basil just before serving for a bright, fresh finish.
Variation
- Add cooked pasta (8 ounces of penne or ziti) to the chicken and sauce mixture to turn this into a heartier chicken Parm pasta bake.
- Swap mozzarella for an Italian cheese blend or add provolone for extra stretch and a slightly sharper flavor.
- Make it a veggie-packed version by folding in 1–2 cups of sautéed spinach, mushrooms, or bell peppers before baking.
Cooking Notes
- If using cold chicken from the fridge, expect the full bake time so the casserole heats through completely.
- Use dry breadcrumbs rather than panko if you want a finer, more traditional chicken Parmesan–style crust; panko will give a lighter, extra-crunchy top.
- If the top browns too quickly, loosely tent the dish with foil for the last 5–10 minutes of baking.
Serving Suggestions
- Serve over cooked spaghetti, penne, or your favorite pasta to mimic classic chicken Parmesan with far less work.
- Pair with a crisp green salad and garlic bread or warm dinner rolls for a complete Italian-inspired meal.
- Add a side of roasted or steamed vegetables, such as broccoli, green beans, or asparagus, to balance the richness of the casserole.
Tips
- Taste your marinara and adjust seasoning with a pinch of sugar, salt, or red pepper flakes before mixing if needed.
- For extra crunch, mix a tablespoon of melted butter into the breadcrumb topping along with the olive oil.
- To prep ahead, assemble the casserole up to the point of baking, cover tightly, and refrigerate for up to 24 hours. Add 5–10 minutes to the baking time if going straight from the fridge to the oven.

Frequently Asked Questions
- Can I use uncooked chicken in this casserole?
This recipe is designed for cooked, shredded chicken. If you only have raw chicken, cook and shred it first (bake, poach, or pan-cook), then proceed with the recipe. - Can I make this casserole ahead of time?
Yes. Assemble the casserole, cover tightly, and refrigerate up to 24 hours in advance. Bake as directed, adding a few extra minutes if needed until hot and bubbly. - Can I freeze Chicken Parmesan Casserole?
You can freeze it before baking by wrapping tightly and freezing for up to 3 months. Thaw overnight in the refrigerator, then bake until heated through and the top is golden. - What kind of breadcrumbs work best?
Italian-seasoned breadcrumbs add extra flavor, but plain breadcrumbs work well too. Just bump up the Italian seasoning or add a pinch of garlic powder for more taste.
